NHTSA Complaint #11522704 — 2017 MAZDA CX-5

What component or system failed or malfunctioned, and is it available for inspection upon request? Sudden loss of power (and speed) on interstate highway at ~65 mph. Fuel level was under 1/4 tank level. Weather was clear and approx. 60-70 deg F. Cruise control was on and vehicle working normally for hours on the road trip with cruise control on and functioning properly on the highway. Suddenly, the vehicle lost power, check engine light came on, and vehicle was running very sporadic. P0192 code thrown. Low fuel pressure which resulted in car suddenly going into reduced power mode. Sudden loss of high pressure pump would have resulted in complete loss of propulsion, which did not occur in this case - this indicates low pressure from the in-tank LP fuel pump. How was your safety or the safety of others put at risk? Sudden and unexpected loss of power on the highway which could have resulted in rear end accident or loss of control while trying to get the vehicle off the highway. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes - if fuel tank level gets below 1/4 tank the problem will occur. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? No. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No - sudden loss of power and then engine light came on (constant, not flashing) and vehicle had sporadic power issues until we could get off the highway. Certified technician put scanner on car. Code was P0192 - low fuel rail pressure. Filled fuel tank to full, cleared code, and continued to drive car. Issue did not reoccur until fuel level fell below 1/4 level (approx.). 2017 Mazda CX5 is believed to have the same or similar low pressure fuel pump in tank, OEM = Denso, which is on recalled Mazda models from 2018 and newer. I believe older models of Mazda's with the same pumps should also be recalled!
